Raphael Bousso is the Chancellor’s Chair in Physics at the Berkeley Center for Theoretical Physics, where he leads the Bousso Group in research on quantum gravity and quantum information. He is a renowned string theorist famous also for his development of the string theoretic landscape and the Bousso bound in holography. In this episode, Robinson and Raphael discuss the groundbreaking work of Jacob Bekenstein, Stephen Hawking, Leonard Susskind, Gerard ’t Hooft, and others on the black hole information paradox. They then turn to how this led to the formulation of the holographic principle, which has had profound implications for research on quantum gravity, especially for Raphael himself, who has recently been working on quantum information theory, quantum communication, and other ways in which classical gravity “knows about” and encodes its own quantum states.
